DURAG volume flow measurement systems provide accurate, contactless monitoring of gas flow for emission control and process optimization, even in humid, high-temperature industrial environments.
DURAG GROUP offers a range of volume flow measurement systems designed for continuous, contactless monitoring of gas flow in industrial applications. These systems are essential for both emission monitoring and process control, providing accurate data even under challenging conditions such as humid, aggressive, or high-temperature gas streams.
In industrial plants, measuring the volume flow of flue gases is critical not only for regulatory compliance but also for optimizing operational efficiency. Volume flow data is used to calculate mass emissions when combined with pollutant concentration values, making it a key parameter in environmental reporting and control strategies.
DURAG systems typically use the ultrasonic transit time difference method, which enables in-situ, contactless measurement of gas velocity across the full duct diameter. This velocity data is then used to calculate the volume flow. Systems can be configured to measure both operational and standardized volume flow, with optional sensors for temperature and pressure compensation.
Whether for small ducts or large-scale industrial stacks, DURAG volume flow measurement systems deliver precise, reliable data to support safe, efficient, and compliant operations.
